Lars Ulrich is the drummer and co-founder of Metallica.
In 1981, Ulrich met James Hetfield in Downey, California and formed the thrash metal band Metallica. Ulrich’s early work with Metallica led him to be dubbed as one of the thrash metal scene’s drumming greats. He became known for his pioneering fast thrash drum beats and techniques featuring on many of Metallica’s early songs, such as “Metal Militia,” “Fight Fire with Fire,” “Dyers Eve,” and “Battery.” He has since been considerably influential due to both the popularity of his band and his interesting drum techniques and styles such as the machine-gun double bass in the song “One” and the pounding opening of “Enter Sandman.”
In 2000, Ulrich faced criticism when he was one of the first artists to take direct action against Napster, which was the first site that allowed people to download music off the Internet. In July 2000, Ulrich testified before the Senate Judiciary Committee after Metallica’s entire catalogue was found to be freely available for download on the service. There was mass outcry from Napster users. No one ended up getting sued for copyright infringement, and the case was settled out-of-court.
